Thanks for your response. In developing the product, SunZag’s optical strip method tested unrecoverable by CD recovery companies. Discs were tested with only 1 strip on the surface - sure, you can apply more strips if you’d like, since it only takes 2 seconds to do…BUT since the data is encoded DIGITALLY, one strip is all that is required. This is an amazing breakthrough, there is no need to destroy every bit of data on CDs since that is overkill for digital systems (unlike an old record, which is analog, you’d need to destroy everything). The Disc Eraser works because the optical strip is thick enough, and precisely applied at the most effective skew angle. Therefore, it is much more effective than using a blade to randomly scratch up the surface. The Disc Eraser is surprisingly simple because it’s based on digital data destruction, not physical…and it promotes CD recycling rather than creating ewaste particles, which is what breaking, cutting up, and shredding does.

I don’t doubt that this renders the disc unreadable, but for $13, I’d rather that it was the kind that spirals cuts all over the surface of the disc, thus ensuring that it’s even harder to recover the data. If you just used that line-cut one in the video once, there’s still quite a bit of data that could potentially be retrieved from the extremely large un-cut area.

Still, it’s good enough for home use and people who don’t have to wear tinfoil hats ;)

I’m sure it’s worth $12. But your video review? Dude, you’re running a gadget blog - please tell me you can do better than that!
